No display at all after starting to boot machine

Hello all

I really hope someone can help me cos this is a bit serious.

I just got in, put my qubes machine on and selected the boot menu to get into qubes. I get the graphics there so I can tell from that there is no issue with my display equipment. After I choose the qubes os from the menu it just goes.to a black screen, no dialogue box to decrypt my hard disk or anything.

If I put the type the key in the disk drive light shows activity.and I can hear the drive working but there is nothing on the screen.

Would really appreciate help as I use this machine for work.

Thanks in advance

Update
I managed to get in by going to the advanced options on the boot menu and selecting a previous version of the hypervisor.

It would be nice if it just worked like it did prior to the latest dom0 update, which I remember I updated last night, any workarounds or commands I need to run? Now I’m able to interact with my system I can give more technical info

What’s the Xen and kernel version that works for you and that’s not working for you?
Maybe you can try to remove the kernel that is not working for you and update the dom0 again so it’ll be reinstalled in case there was an issue during the installation.

Have the same issue on 2 machines, last kernel works fine.
Another 2 machines boot but still get a black screen after they enter xscreensaver…

Pretty sure something in last latest update is broken.

Try to switch to another TTY using Ctrl+Alt+F2 and if you see the console then try to login and check the logs to see what is failing.

What is the machine hardware (CPU/GPU)?
I’ve been experiencing this since kernel 6.10.7 (6.10.6 and earlier works), same for the 6.6 series starting with 6.6.48.

Didn’t try that. Will just use the older kernel until the next update. Will do some debugging if that’s also broken

I also have a GTX 1070.

It has probably been fixed upstream with this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=46040ea8a6a58e5645d91ffa3ead7ed8fd633d56

nouveau:

  • fix GP10x regression on boot

The next kernel release should include it.
